Abstract

The invention provides a humerus prosthesis. The humeral prosthesis includes a humeral head cap body, including a spherical outer wall surface and an inner wall surface located in the spherical outer wall surface, and the inner wall surface includes a top wall and an annular side wall connected with the top wall; the intramedullary column is connected with the humeral head cap body, and the medulla The top of the inner column is located in the cap body of the humerus head; wherein, a tapered surface matching structure is provided between the annular side wall and the intramedullary column, and the cap body of the humerus and the intramedullary column are connected through the tapered surface fitting structure. The technical scheme of the invention effectively solves the problem in the related art that the artificial shoulder joint prosthesis with a handle is easy to cause injury to the patient.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a humeral prosthesis. Background technique [0002] Periarthritis of shoulder is referred to as periarthritis of shoulder, commonly known as Ningshoulder or Fifty Shoulders. Periarthritis of shoulder is the common disease that is main symptom with shoulder arthralgia and inconvenient activity. The high incidence age of this disease is about 50 years old, and the incidence rate of women is slightly higher than that of men, and it is more common in manual laborers. If it is not treated effectively, it may seriously affect the functional activities of the shoulder joint. Shoulder joint can have extensive tenderness, and to cervical region and elbow radiation, also can occur the atrophy of deltoid muscle in various degrees. [0003] The treatment plan for frozen shoulder in the related art is: adopt the artificial shoulder joint prosthesis with handle, need to resect the h...
